“If you want to spend a few days experiencing the hillside,” you should use the services of a guide, recommends That Backpacker. Sure, “there are full-day hikes and even half-day hikes (like Cat Cat Village) which you may want to attempt on your own,” but hiring a local guide “who is familiar with the terrain, the changes in weather, and the best lookout spots” is recommended. If you want to be “really spontaneous,” you can turn up to Sapa in the morning and book a day trek then and there, says Just Globetrotting, “but to get the most out of your time we recommend booking a trek in advance with a reputable company and opt for at least a 1-night homestay in one of the villages.”
